1936] MAMMALS OF OREGON 165 



Breeding habits. Specimens taken have the usual 4 pairs of 

 mammae 1 inguinal, 2 abdominal, and 1 pectoral, or, as sometimes 



fiven, 3 abdominal and 1 pectoral, because the posterior pair is so 

 ar forward as to be readily classed as either inguinal or abdominal. 

 Although there seem to be no records of young of this form from 

 Oregon, 3 to 6 young are common to this group. 



GLAUCOMYS SABRINUS KLAMATHENSIS (MEEBIAM) 

 KLAMATH FLYING SQUIRREL; KOK-KOTCH of the Klamath (C. H. M.) 



Sciuropterus alpinus klamathensis Merriam, Biol. Soc. Wash. Proc. 11 : 225, 

 1897. 



Type. Collected at Fort Klamath, Oreg., by B. L. Cunningham, January 

 11, 1897. 



General characters. Slightly larger than fuliginos,us t and paler. Upper parts 

 washed with light brown or cinnamon drab over plumbeous ; tail dusky toward 

 tip ; eyering dusky ; cheeks clear gray ; lower parts creamy white or buffy ; 

 soles of hind feet yellowish. 



Measurements. Total length, 319 mm; tail, 144; hind foot, 41; ear (dry), 19. 



Distribution and habitat. This is the flying squirrel of the yellow- 

 pine forest east of the Cascade Mountains, at least from the Paulina 

 Mountains south to the Klamath country (fig. 31). There are speci- 

 mens from Paulina Lake, Davis Creek, Fort Klamath, Sun Creek, 

 and Crater Peak (4 miles south of Crater Lake), and Upper Klamath 

 Lake. It is probable that the form inhabits the whole length of the 

 yellow pine east slope of the Cascades in Oregon. 



General habits. Luther Goldman, in August 1914, reported flying 

 squirrels at Paulina Lake and along Paulina Creek and collected a 

 specimen at a hollow tree, where it evidently came for the rain water 

 held in a cavity of the trunk. 



Harry Telford, in February and March 1914, obtained specimens 

 from a marten trapper 8 miles north of Fort Klamath, where they 

 proved very troublesome by getting into the marten traps. About as 

 many flying squirrels as pine squirrels were caught. The 3 males 

 secured showed sexual development indicating the presence of the 

 breeding season, but the 2 females did not show signs of embryos.

Type. Collected at Raymond, Idaho County, Idaho, March 8, 1897, by Harbi- 

 son and Benjamin. 



General characters. Slightly grayer than typical sabrinus, smaller than any 

 other of the Rocky Mountain forms of the group. Upper parts in winter fur 

 pale wood brown, sometimes tinged with vinaceous cinnamon, feet pale brown, 

 shading to grayish brown, or on the toes to grayish white; tail above wood 

 brown, more or less tinged with cinnamon and hair brown ; under parts whitish, 

 strongly washed with pinkish cinnamon ; summer pelage more yellowish.

 Total length, 315 mm ; tail. 142 ; foot, 39.5. 



Distribution and habitat. Western Wyoming and Montana across 

 Idaho and into the Blue Mountain section of Oregon. There are 

 specimens from Anthony and Wallowa Lake in the Wallowa Moun-
